	Title	Dimensions of stimulus complexity			Type	Journal Article
	Year	1996	Publication	Journal of Experimental Psychology. Animal Behavior Processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	22	Issue	1	Pages	3-18
	Keywords	Animals; Behavior, Animal; Cognition; Learning; Memory; Time Factors
	Abstract	Animal learning research has increasingly used complex stimuli that approximate natural objects, events, and locations, a trend that has accompanied a resurgence of interest in the role of cognitive factors in learning. Accounts of complex stimulus control have focused mainly on cognitive mechanisms and largely ignored the contribution of stimulus information to perception and memory for complex events. It is argued here that research on animal learning stands to benefit from a more detailed consideration of the stimulus and that James Gibson's stimulus-centered theory of perception serves as a useful framework for analyses of complex stimuli. Several issues in the field of animal learning and cognition are considered from the Gibsonian perspective on stimuli, including the fundamental problem of defining the effective stimulus.

	Title	Imitative learning in Japanese quail (Coturnix japonica) depends on the motivational state of the observer quail at the time of observation			Type	Journal Article
	Year	2001	Publication	Journal of comparative psychology (Washington, D.C. : 1983)	Abbreviated Journal	J Comp Psychol
	Volume	115	Issue	1	Pages	62-67
	Keywords	Animals; Behavior, Animal; Coturnix; Female; Imitative Behavior; Learning; Male; *Motivation; Reinforcement (Psychology); Time Factors
	Abstract	The 2-action method was used to examine whether imitative learning in Japanese quail (Coturnix japonica) depends on the motivational state of the observer quail at the time of observation of the demonstrated behavior. Two groups of observers were fed before observation (satiated groups), whereas 2 other groups of observers were deprived of food before observation (hungry groups). Quail were tested either immediately following observation or after a 30-min delay. Results indicated that quail in the hungry groups imitated, whereas those in the satiated groups did not, regardless of whether their test was immediate or delayed. The results suggest that observer quail may not learn (through observation) behavior that leads to a reinforcer for which they are unmotivated at the time of test. In addition, the results show that quail are able to delay the performance of a response acquired through observation (i.e., they show deferred imitation).

	Title	Postconflict behavior in captive western lowland gorillas (Gorilla gorilla gorilla)			Type	Journal Article
	Year	2006	Publication	American journal of primatology	Abbreviated Journal	Am. J. Primatol.
	Volume	68	Issue	8	Pages	789-801
	Keywords	Animals; Behavior, Animal; Competitive Behavior; Conflict (Psychology); Female; Gorilla gorilla/*physiology/psychology; Male; Time Factors
	Abstract	Postconflict (PC) behaviors, including reconciliation and consolation, have been observed in many primate and several nonprimate species. Using the PC-matched control (MC) method, PC behavior was examined in two groups (n=13) of captive western lowland gorillas, a species for which no conflict resolution data have been published. Analyses of 223 conflicts showed significantly more affiliation between former opponents after a conflict when compared to control periods, indicating reconciliation. Results also showed significantly more affiliation between the victim and a third-party after a conflict, indicating consolation. Both solicited and unsolicited consolation were observed. The majority of the affiliative interactions observed for both reconciliation and consolation were social proximity, which suggests that unlike most nonhuman primates, proximity, rather than physical contact, may be the main mechanism for resolving conflicts in western lowland gorillas. PC behavior was not uniform throughout the groups, but rather varied according to dyad type.

	Title	Interruptions improve choice performance in gray jays: prolonged information processing versus minimization of costly errors			Type	Journal Article
	Year	2002	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	5	Issue	4	Pages	209-214
	Keywords	Animals; Behavior, Animal; Choice Behavior; Female; Learning; Male; Models, Biological; Motivation; Reinforcement Schedule; Songbirds/*physiology; Time Factors
	Abstract	Under the assumption that selection favors minimization of costly errors, erroneous choice may be common when its fitness cost is low. According to an adaptive-choice model, this cost depends on the rate at which an animal encounters the choice: the higher this rate, the smaller the cost of choosing a less valuable option. Errors should thus be more common when interruptions to foraging are shorter. A previous experiment supported this prediction: gray jays, Perisoreus canadensis, were more error prone when subjected to shorter delays to access to food rewards. This pattern, though, is also predicted by an attentional-constraints model. Because the subjects were able to inspect the rewards during delays, their improved performance when subjected to longer delays could have been a byproduct of the experimentally prolonged opportunity for information processing. To evaluate this possibility, a follow-up experiment manipulated both delay to access and whether rewards could be inspected during delays. Depriving jays of the opportunity to inspect rewards (using opaque lids) induced only a small, nonsignificant increase in error rate. This effect was independent of length of delay and so the jays' improved performance when subjected to longer delays was not simply a byproduct of prolonged information processing. More definitively, even when the jays were prevented from inspecting rewards during delays, their performance improved when subjected to longer delays. The findings are thus consistent with the adaptive-choice model.

	Title	Selective suppression of drinking during a limited period following aversive drug treatment in rats			Type	Journal Article
	Year	1977	Publication	Journal of Experimental Psychology. Animal Behavior Processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	3	Issue	1	Pages	66-76
	Keywords	Animals; Avoidance Learning; Awareness; Conditioning, Operant; Dose-Response Relationship, Drug; Drinking Behavior/drug effects; Lithium/poisoning; Male; Osmolar Concentration; Rats; Saccharin/administration & dosage; Taste; Time Factors
	Abstract	Administration of lithium chloride disrupted the intake of flavored solutions but not water in rats. This intake suppression was directly related to the amount of lithium administered (Experiment 1), occurred with both palatable and unpalatable novel saccharin solutions (Experiment 2), but was only observed if subjects were tested starting less than 75 min. after lithium treatment (Experiment 3). Twenty-five daily exposures to saccharin did not attenuate the effect (Experiment 4). However, in saccharin-reared and vinegar-reared rats, lithium did not disrupt consumption of the solutions these subjects had access to throughout life, even though suppressions of intake were observed when these subjects were tested with novel flavors (Experiment 5). The selective disruption of drinking is interpreted as a novelty-dependent sensitization reaction to the discomfort of aversive drug administration.

	Title	Timing in pigeons: effects of the similarity between intertrial interval and gap in a timing signal			Type	Journal Article
	Year	2002	Publication	Journal of experimental psychology. Animal behavior processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	28	Issue	4	Pages	416-422
	Keywords	Animals; Attention; Columbidae; Conditioning, Operant; Discrimination Learning; Mental Recall; Probability Learning; Reinforcement (Psychology); Reinforcement Schedule; Retention (Psychology); Time Factors; *Time Perception/physiology
	Abstract	Previous research suggests that when a fixed interval is interrupted (known as the gap procedure), pigeons tend to reset memory and start timing from 0 after the gap. However, because the ambient conditions of the gap typically have been the same as during the intertrial interval (ITI), ambiguity may have resulted. In the present experiment, the authors found that when ambient conditions during the gap were similar to the ITI, pigeons tended to reset memory, but when ambient conditions during the gap were different from the ITI, pigeons tended to stop timing, retain the duration of the stimulus in memory, and add to that time when the stimulus reappeared. Thus, when the gap was unambiguous, pigeons timed accurately.

	Title	Reversibility of action and safety during pregnancy of immunization against porcine zona pellucida in wild mares (Equus caballus)			Type	Journal Article
	Year	2002	Publication	Reproduction (Cambridge, England) Supplement	Abbreviated Journal	Reprod Suppl
	Volume	60	Issue		Pages	197-202
	Keywords	Animals; Animals, Wild; Antigens/administration & dosage; Contraception, Immunologic/methods/veterinary; Egg Proteins/administration & dosage; Female; Fertility; Horses; Immunization, Secondary/veterinary; Membrane Glycoproteins/administration & dosage; Population Control; Pregnancy; Receptors, Cell Surface; Safety; Swine; Time Factors; Vaccines, Contraceptive/*administration & dosage
	Abstract	Contraceptive management of publicly valued wildlife species requires safeguards to ensure that these populations are preserved in a healthy state. In addition, reversibility of contraceptive effects and safety in pregnant animals are major concerns. A population of wild horses has been immunized against porcine zona pellucida (PZP) over a 12 year period on Assateague Island National Seashore, MD (ASIS). Mares initially received one or two 65 microg inoculations and once a year 65 microg booster inoculations, all delivered by dart. All young mares aged > 2 years were treated with PZP for 3 consecutive years regardless of whether they have bred successfully and they were then removed from treatment until they had foaled. All mares vaccinated for 1 or 2 consecutive years became fertile again and 69% of mares treated for 3 consecutive years returned to fertility. All five mares treated for 4 or 5 consecutive years have also returned to fertility, but over longer periods of time. Mares treated for 7 consecutive years have not returned to fertility, but several, while still infertile, have started ovulating again. There was no difference in survival rates between foals born to treated and untreated mares, and PZP treatment of pregnant mares did not affect subsequent fertility of their female offspring.

	Title	Management factors associated with stereotypic and redirected behaviour in the thoroughbred horse			Type	Journal Article
	Year	1995	Publication	Equine veterinary journal	Abbreviated Journal	Equine Vet J
	Volume	27	Issue	2	Pages	86-91
	Keywords	Animal Husbandry/methods; Animals; Horse Diseases/psychology/therapy; Horses; Risk Factors; *Stereotyped Behavior; Time Factors
	Abstract	A greater knowledge of the effect of management factors is required to investigate the ontogeny of abnormal behaviour in the stabled horse. A postal survey of racehorse (flat) trainers yielded information about 22 yard and management factors. The relationship of the factors to the prevalence of abnormal behaviour was analysed by logistic regression. Management factors related to the time spent in the stable showed the strongest associations with stereotypic behaviour. The risk of horses performing abnormal behaviour increased: 1) as the amount of forage fell below 6.8 kg/day, 2) when bedding types other than straw were used, 3) when the total number of horses on the yard was fewer than 75, 4) in association with box designs that minimised contact between neighbouring horses, 5) when hay, rather than other types of forage, was used.
